To all whom #may concern.'

Be it known that'l, Geenen il. Biiiiitiiann'r, citizen of the United States, residingr at Burlingame, in the county ot San Mateo and State ot California, have invented new and useful Improvements in Toilets, ot which the following' is a speeiiicatioii.

My invention relates to toilets. lts object is to provide a disappearing toiletI which can be placed in any room and moved into and out of a cabinet, being only exposed when desired tor use 5 which will have no flush tanks, floats or ordinary valve arrangements, "and which will be simple in construction, sanitail'y, ndniot likely to get out of order.

rllidiiiveiitloriconsists ofthe .parts and cthe Iconstri'iction and combination ot' parts as `here'i'riatte: more fully described and elaimed, liavin reference to the accompany* ing` drawings, in wliich- Figure l is a side elevation in partial section of the ini" ion. Fig. 2 is a plan view v. ot' the saine/1 i hiechanisrn for the flushing arrangement.

represents a bowl ot' suitable construction 'havingl a suitably packed ball-bearingr eve joint 2 suitably mounted to turn on the-waste pipe 3 so that the bowlniiiay be swung from side to side and moved into or i'iut otfa suitable cabinet el, which latter may finto the wall ofthe building or 4 is a water supply pipe connecting` with tli'e main, or any othei suitable soiii'ce of supply, and through which the water is admitted in to the bowl for thishiiig purposes. enters a vertically arranged cylinder (i which has a horizontal cylindrical extension 7, in which extension a suitably packed piston 8, is adapted to operate. Avalve 9 seats iii theupper end of the cylinder 6, and the stem 10 of this valvecarries a roller 11 adapted to ride on the rod 12 of piston S. rlliis pistoii-i'od 12 has a cani or wedge 1*), suitably positioned to engage the roller 11 so that when the rod 12 is pulled in one direction it will lit't valve 9 and allow the water to tlow trom the pipe 5 into the valve casing` 6; the valve 9 being closed automatically in a manner shortly to be described. The stem 10" of valve 9 passes ondown through the hollow stein 1t of a lower regulatine; valve 15, which is movable toward from its seat 1.6 at the lov-.fer end ot the valve casiiigt; the lower end ot the Yalve g. 3 is a detail of a valvel l casinpY opening` into a short pipe 1T disposed in axial line with the pivoted sleeve/2 ofv the bowl. rl`liis pipe 1T t'oims a pivot for the 15 are open, andthe bowl swung' out into the room into operative position, the water can pass directly down through the'valve casing` t3 and through pipes'lT and 1S into the bowl, and thence into the vaste-pipe. The valve 15 is mounted loose on-the stein l() so as to'be movable independent of valve 9. The lunetion ot' the valve 15 is that of a regulator t govern the tlow ot the water into the bowl,- and its adjustment is effected by suitable means, as the ratchet 1S) operated The rear end ot' the casing extension 7l is closed, and .the piston S has a small port 21 connecting the space on the opposite sides of the piston, through which the tluid may slowly circulate. inally to press the piston 8 outward from the valve stem 1() so as to allow the valve 9 with the top of the waste-pipe 3 and leads outsideV the building, so as to remove any noxious gases that might be `generated.

Any appropriate means may be employed to elfect the oscillation of the toilet into and out of the casing. As here shown, the sleeve 2 carries a xed mutilated gear 24, engaged by a coi-responding segmental rack Q5, which latter is carried o'n a lever 2G fulcruined at Q6. The lever 26 is connected by a link 7 to the bell `crank 27. A handoperating lever 28 is connected with av bell crank Q7 by a link 28, thus it will be seen the parts; will bc operated to move the device into the casing, and when the lever is moved in the opposite'direction the bowl will be swung outward into operative position so as to open up communication between the stack pipe and the bowl through the port 9.9.

it is understood that the,bowl and the stack pipe are only in communication through the passageway 29 when the bowl is swung` outward into operative position. Whenever it is swung inward into the cabinet, this opening 29 is closed, valve-tashion, by the turning sleeve 2 so that the gases troni the stack-pipe cannot pass into the room.

ln operation, the door of the cabinet is by a conveniently arranged tliuinb-screw 20.'

to close. A suitable ventfpipe n3 is connected y tlushina pipe 1S which connects with the top ot the bowl, so that when valves 9 and' that by rocking the lever 28 in one direction, l

vthe bowl opened and the bowl swung outward into the position shown in Fig. 1, or in dotted line position, Fig. 2. Assuming 'that the thumb-screw 20 and ratchet 19 have been turned and set permanently so as to give the desired outlet around valve 15, the operator simply 'pulls outward on the handle 30 which is attached to the piston-rod 12. This causes the cam 13 to lift up on roller 11, opening valve 9. The water can then pass in from pipe 5 around valve 9, through the casing, and out around valve 15 and through the pipes 17-18 into the bowl; thence to the sewer. Releasing the hold on thehandle 30 allows the spring 22 to act, and the period of flushing will depend on the time that it takes this spring to push the piston 8 back ward against the slow ow of the fluid through port 21 from the space behind piston 8 it being understood that the combined pressure 'Xerted on piston 8 by the water pressure in the casing and the spring 22, is in excess of the pressure at the outlet into ipe 17. As soon as the-cam 13 ridesout rom underneath the roller 11, the valve` 9` is seated by the pressure in pipe 5, and the flushing operation ceases.

i This application is a division of original application upon which there has been issued to me Patent 7 1909,

Having thus described my invention, what I claim and desire to secure by Letters- Patent, is-- 1. In a toilet, lthe combination of a stackpipe, a bowl having a collar-bearing turnable in suitable bearings on said stack-pipe, means by which the stack-pipe and bowl are in communication one position and out of communication when stands in another position, and means for admitting water to the bowl for flushing purposes, said last means comprising a cylinder having a horizontal extension and an inlet and outlet valveat opposite points one on each side of said extension, a piston operating in the extension and adapted to actuate said valves during its movement, and means for operating the piston.

2. In a toilet, the combination of a stackpipe, a bowl havingacollar-bearing turnable in suitable bearings on said stack-pipe, means by which the stack-pipe and bowl are in No. 993,619 dated September.

when the bowl stands in through the hollow pivot of said flushing i i e said ,last namedmeans com risin a P a cylinder having a horizontal extension intermediate of its ends, and having an inlet at Aone side of said extension'and an outlet at the other side, valves controlling said inlet and outlet and a piston operating in said extension cross-wise of the valves and having means for operating the valve during its movement.

3. In a toilet, the combination of a stackipe, a bowl having a collar-bearing turnable m suitable bearings on said stack-pipe, means by which ,the stack-pipe and bowl are in communication when the bowl stands in one position, and out of communication when Y,

the bowl stands in another position, means including a mutilated gear connected with the bowl and a mechanism for operatng the same to induce rotary motion to the bowl a flushing pipe entering the bowl and turning on a hollow pivot co-aXial with the pivot of said sleeve, means for admitting-water through the hollow pivot of said flushing pipe, and a vent-pipe connected with the stack-pipe back of the bowl and adjacent to said sleeve.

4. In a toilet, the combination of a. stackpipe, a bowl having a collar-bearing turnable in suitable bearings on said stack-pipe, means by which the stack-pipe and bowl are in communication when the bowl stands in one position, and out of communication when the bowl stands in another position, means for admitting water to the bowl for flushing GEORGE J.
